Ok. That problem was decided on the work PC. But I have simular problem on my home PC. Screenshot attached. install nrf go studio with 5.12 J-flash. nrf works good. But when keil try to flash - screenshot. For keil on the win 10 needs newer dll. I think this not due to chinese j-link. This problem of settings.

Hard to say what the problem could be. Make sure you have the same versions of your software and drivers on both computers.
Also, the problems you are experiencing are most likely linked to the Chinese J-link clone you are using.
Best regards.

ok. I reinstalled nrf gostudio. Also with it installed 5.12f j-link. In the folder j-link I have JLinkARM.dll. Nrf go studio need this dll. Screen attached. How to set this dll into nrf go studio?

Then my guess is that your problems is related to the chinese j-link clone. A tip might be to get a nRF52-DK and use the OB J-link programmer.
If you can't get it to work because of the updated J-link driver, you can always uninstall and go to SEGGER's website and download the older version you had.
Best regards.

sorry, I use chinese j-link clone (( S/N I can set any. But on my work PC after test I can't to restore work variant. Before it works fine.

Yes, I understand. But are you using a Nordic nRF52-Development kit?
The S/N of 12345678 looks peculiar, and if you are using an external programmer instead of the OB-Jlink on the nRF52-DK, that might be the cause of the problem.
You could try to follow the advice in the message you get, and send a support request to SEGGER's email-address.

I flash via nrf gostudio. I reinstall on my work computer for demonstrate to you and can't return back) Doesn't work. If driver new, screen like attached.

Ok, I see.
Are you using a Nordic nRF52-DK or are you programming your device with a stand-alone SEGGER j-link programmer?

with 6.20h same behavior. screenshot like attached before.

I have never seen that error before, but as it occured when updating the Jlink driver, I would say that is the cause. You could try to reinstall nRFGo Studio and the Jlink driver and see if that helps. I also think there is a later version of the Jlink driver available from SEGGER's website (6.20h).
If that doesn't help, you could try to downgrade to an older version of the driver, i.e 6.18.

Joakim Jakobsen — Tue, 07 Nov 2017 12:20:45 GMT

Ok. If it works correctly, it's no point in uploading the screenshot. Glad it works.

RE: keil flash nrf52 problem

Mikhail — Tue, 07 Nov 2017 12:17:31 GMT

You can just press "edit" on your original question and insert the screenshot there.

Mikhail — Tue, 07 Nov 2017 12:12:59 GMT

In evening i'll send screenshot. But I don't know how to insert here this screenshot.

What kind of error do you get when using nrfgo studio? Maybe you could post a screenshot?
I'm using 6.20b myself, and I dont have any problems.

RE: keil flash nrf52 problem

Mikhail — Mon, 06 Nov 2017 15:56:16 GMT

Yes. I have errors when I flash SD via nrfgo stidio. 6.20b doesn't support ... it means that nrf go studio works only with 5.12 ???

RE: keil flash nrf52 problem

Joakim Jakobsen — Mon, 06 Nov 2017 15:53:27 GMT

That should be the latest version. When you have both the command line tools and nRFGo studio installed, you should be all set.
Do you get any errors when trying to flash your softdevice/application using nRFGo Studio?

RE: keil flash nrf52 problem

nrfgostudio_win-64_1.21.2_installer

tell me a sequence for install. step by step. What should I install for win 10 after keil?

RE: keil flash nrf52 problem

Joakim Jakobsen — Mon, 06 Nov 2017 15:43:35 GMT

What version of nRFGo studio are you using? You could try to update to the latest version of that too.

RE: keil flash nrf52 problem

Mikhail — Mon, 06 Nov 2017 15:25:39 GMT

almost. I updated to the last version- 6.20b and now via keil- ok. Via nrf go studio- not ok. Or should be update only command line?

RE: keil flash nrf52 problem

Joakim Jakobsen — Mon, 06 Nov 2017 15:02:52 GMT

Then I would suggest that you update to the latest version and see if that helps solve the problem.
